“The Last Question,” by Isaac Asimov
Asimov believed “The Last Question” to be the best short story he ever wrote. Now you can read it online, without even having to make a trip to the library.
The last question was asked for the first time, half in jest, on May 21, 2061, at a time when humanity first stepped into the light. The question came about as a result of a five-dollar bet over highballs, and it happened this way…
This story is the epitome of high-concept “hard” science fiction. The narrative spans a few trillion years of human history in about 4,500 words and pursues big answers to the big questions. That it can do this without alienating or boring less scientifically-minded readers is a testament to Asimov’s skill. Along the way it touches on the concepts of transhumanism and posthumanism, but its ultimate target is much larger and more impressive.
The central premise of the story — humanity invents an artificially intelligent machine capable of solving its thorniest problems, but the biggest problem of all proves insoluble time and again — is a set up for an ending with more punch than almost anything else in the genre.
“Ask Multivac.”
“You ask Multivac. I dare you. Five dollars says it can’t be done.”
Adell was just drunk enough to try…
You owe it to yourself to read this story.

I’m not sure what you’re asking, Rick. Could you be more specific?

this was a fantastic read. So thought provoking. Does anyone know if asimov was religious?

According to this essay, Asimov wasn’t hostile to religion but vehemently argued against fundamentalism. He was, himself, an atheist.

Thanks for making this story available. I was trying to remember the wording just before the famous punch line. Sadly, my memory is fast failing me. So I went in search of one of my copies of “Nine Tomorrows.” I could not find one. (This is what happens when you share a small house with over 6,000 books.)
The good doctor may have considered this the best short story he ever wrote, but he was being too modest. (Now that’s hard to believe!) It was, and still is, the greatest science fiction short story ever written.
